A model for deformable roll coating with negative gaps and incompressible compliant layers [PDF]

, 2003
A soft elastohydrodynamic lubrication model is formulated for deformable roll coating involving two contra-rotating rolls, one rigid and the other covered with a compliant layer. Included is a finite-strip model (FSM) for the deformation of the layer and
